Lakers backup point guard Steve Blake is out indefinitely after being diagnosed with the chicken pox on Tuesday morning.

The team learned of Blake’s condition after the team’s shootaround in preparation for Tuesday’s game against San Antonio. He’ll very likely miss Wednesday’s game at Sacramento as well in advance of the playoffs, which start either Saturday or Sunday. Blake will be monitored throughout the week.

Meanwhile, Matt Barnes is having soreness in the knee that kept him out of 28 games, and is listed as “questionable” heading into the Spurs game.
